END CAP 2x2

🔧 Main Function

The primary purpose of a 2x2 square cap plug is to:

1. Seal the Open Tube End
   • Prevents water, dirt, mud, and road debris from entering the tubing.
   • Reduces internal rust and corrosion.
2. Protect Against Damage
   • Shields sharp metal edges from bending or denting.
   • Prevents insects or small animals from nesting inside the frame.
3. Improve Safety
   • Covers sharp corners to reduce the risk of cuts or injuries.
   • Creates a smooth finished edge.
4. Enhance Appearance
   • Gives the trailer frame a clean, finished look.
   • Often used on visible ends of trailer tongues or rear bumpers.
